The precious blood of Christ - Τιμιῳ αἱματι· The valuable blood; how valuable neither is nor could be stated.

As of a lamb - Such as was required for a sin-offering to God; and The Lamb of God that takes away the sin of the world.

Without blemish - In himself, and without spot from the world; being perfectly pure in his soul, and righteous in his life.
